Technical Indicators

Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.

Trend Indicators
  • SMA 20 / 50 / 200 — price above = uptrend, below = downtrend. SMA 50 crossing SMA 200 is the golden/death cross.
  • EMA 12 / 26 — faster-reacting averages; 12 above 26 is short-term bullish.
  • MACD — bullish when MACD > signal (green badge), bearish when below. Divergence from price often precedes reversals.
  • ADX (14) — trend strength regardless of direction. <20 range, 20–25 weak trend, 25–50 trend, >50 strong trend.
  • +DI / −DI — +DI > −DI favors bulls; the reverse favors bears. Read alongside ADX.
Momentum Oscillators
  • RSI (14) — <30 oversold, >70 overbought. 40–60 is neutral; trending names can stay extreme.
  • Stochastic %K / %D — <20 oversold, >80 overbought. %K crossing %D is an early momentum signal.
  • Williams %R — inverted scale: <−80 oversold, >−20 overbought.

Oscillators work best in range-bound markets; in strong trends they give premature reversal signals.

Volume & Volatility
  • Bollinger Bands — price at upper band = overbought, lower = oversold. Narrow bands (squeeze) often precede expansion.
  • OBV — cumulative volume; rising OBV confirms uptrend, falling OBV confirms downtrend. Divergence from price is a warning.
  • Vol SMA 20 / Vol ROC — today's volume vs. 20-day average. Positive ROC with price move = conviction.
  • ATR / True Range — average daily $ move; sizing and stop-loss reference.
  • HV 20 / 30 / 60 — realized (historical) volatility. Compare to IV on the options cards: IV > HV = rich premium.

Confluence matters: trend + momentum + volume agreeing carries far more weight than any single indicator. For how these feed the spread scanner score, see the algorithm docs →

SPMB Stock Analysis Report

State Street SPDR Portfolio Mortgage Backed Bond ETF

Executive Summary

Overall Assessment: NEUTRAL | Confidence Level: 7/10

SPMB is a passively managed mortgage-backed bond (MBS) ETF experiencing technical weakness despite fundamentally sound positioning. The fund presents a defensive fixed-income allocation with extremely low volatility (beta 0.14, stock volatility 0.05) and attractive economics (4.29% yield, 0.04% expense ratio). However, technical signals show deteriorating momentum with a bearish MACD histogram (-0.15), elevated overbought stochastic readings (82.03), and negative on-balance volume (-8.28M). The recent news environment is neutral, reflecting macro uncertainty around bond markets and Fed policy rather than fund-specific catalysts.

Investment Thesis: SPMB offers capital preservation with modest yield in a low-volatility wrapper, making it suitable for defensive positioning. The technical pullback from recent highs combined with strong fund inflows (+12.1% over 12 months) suggests healthy demand despite near-term consolidation. The fund's minimal tracking error cost (0.04% vs 0.39% category median) and concentrated weight in government-backed MBS positions it well for risk-off environments.

Recent News Sentiment Impact: NEUTRAL — All six headlines are dated 2022-2023 and focus on macro themes (Fed policy, recession concerns, bond market outlook) rather than fund-specific developments. The most recent headline (December 2023) discusses potential bond rally scenarios, which is marginally constructive for MBS but offers no actionable catalyst.

Technical Analysis

Trend Direction

| Timeframe | Direction | Assessment | |-----------|-----------|------------| | Short-term (1-4 weeks) | Bearish consolidation | Price $21.38 trades below SMA 50 ($21.62) and SMA 200 ($22.16); trapped between $20.90-$21.57 Bollinger range | | Medium-term (1-3 months) | Downtrend forming | 20-day SMA ($21.23) flattening; EMA 12 ($21.26) barely above EMA 26 ($21.35), suggesting momentum exhaustion | | Long-term (3-12 months) | Neutral with slight bias down | Fund trades $0.78 below its 200-day average; no clear directional conviction |

Support/Resistance Levels

| Level | Type | Significance | |-------|------|--------------| | $20.90 | Support | Lower Bollinger Band; previous consolidation floor | | $21.23 | Dynamic Support | SMA 20 acting as pivot; critical hold to prevent further deterioration | | $21.38 | Current Price | Neutral zone between moving averages | | $21.57 | Resistance | Upper Bollinger Band; psychological resistance | | $21.62 | Intermediate Resistance | SMA 50; break above would signal reversal | | $22.16 | Major Resistance | SMA 200; reclaiming this level would confirm trend exhaustion |

Momentum Signals

RSI (14): 51.52 — NEUTRAL

  • Neither overbought nor oversold; mid-range reading suggests equilibrium between buyers and sellers
  • No momentum divergence apparent; neutral stance appropriate

Stochastic Oscillators: %K 82.03 / %D 72.97 — OVERBOUGHT WARNING

  • %K reading of 82.03 (>70) indicates overbought conditions in fast-moving markets
  • %D at 72.97 confirms momentum is elevated despite price consolidation
  • Potential mean reversion risk if fast stochastics roll over below %D
  • Conflict Alert: High stochastic readings diverge from neutral RSI—suggests short-term momentum stretch despite balanced directional strength

Williams %R: -19.30 — BULLISH EXTREME

  • Deeply negative reading indicates price is very close to recent highs within the lookback window
  • Contrasts with Bollinger Band neutral signal, suggesting intraday volatility rather than directional conviction
  • Minor positive bias vs overbought stochastic concerns

MACD: -0.09 Signal / 0.05 Histogram / -0.15 — BEARISH

  • MACD line (-0.09) remains below signal line (0.05)
  • Histogram at -0.15 (negative and widening) confirms bearish momentum
  • No bullish crossover in sight; suggests continuation of weakness into near term
  • Key Signal: Most reliable bearish technical indicator in current setup

Bollinger Bands: Width 3.16 — NEUTRAL/COMPRESSION

  • Band width of 3.16 is moderate—not in squeeze (would indicate volatility compression before breakout)
  • Price centered near middle band ($21.23) suggests no directional bias from band positioning
  • Upper/lower bands at $21.57/$20.90 define narrow 2.6% trading range

Volume Analysis

Volume SMA 20: 2.78M shares | Volume Rate of Change: -12.67% — DECLINING INTEREST

  • Volume trending 12.67% below 20-day average indicates waning institutional participation
  • Low volume on consolidation typically precedes directional breakout (requires catalyst confirmation)
  • For a bond ETF, lower trading volume is less concerning than for equity securities

On-Balance Volume: -8.28M — NEGATIVE ACCUMULATION

  • OBV deep in negative territory and not recovering suggests net selling pressure despite price stability
  • Indicates institutional redemptions or holder portfolio rebalancing
  • Conflict Alert: Contradicts +$857M inflow data (12-month)—may reflect seasonal distribution or profit-taking after recent gains

Interpretation: Declining volume + negative OBV despite positive fund flows suggests that new money entering the fund is being distributed (dividend reinvestment, allocation) rather than driving price appreciation. This is typical for high-yield bond funds but indicates limited upside catalysts from volume perspective.

Sentiment Assessment

Catalyst Identification

| Catalyst | Timeframe | Likelihood | Impact | |-----------|-----------|-----------|--------| | Fed Rate Decision / Economic Data | Ongoing | High | MBS highly sensitive to rate expectations | | Bond Market Repricing | Ongoing | Medium | Macro theme from Dec 2023 headline | | Fund Distribution / Dividend Adjustment | Quarterly | Medium | Could affect short-term price if yield drops | | Credit Spread Widening | Event-driven | Medium | Could pressure MBS valuations in risk-off | | Mortgage Refinancing Wave | Scenario-driven | Low-Medium | Would pressure fund composition if rates fall sharply |

Market Narrative

Headlines vs Technical Signals ALIGNMENT: MISALIGNED

Stage 3 — Technical Overlay (±50% cap, 5 groups)
Group 1 · Directional Bias (±0.25)
  • RSI <40 bullish / >60 bearish
  • MACD crossover + histogram trend
  • Price vs SMA 50 & SMA 200
Group 2 · Momentum (±0.10)
  • Stochastic %K <20 / >80
  • Williams %R <−80 / >−20
Group 3 · Volatility (up to −0.25 / +0.15)
  • Blended ATR + straddle expected-move penalty
  • Bollinger Band signal (+ counter-trend penalty)
  • BB width — vol contraction boost for ICs
Group 4 · IV Regime (±0.15)
  • IV rank ≥ 75 → strong boost for credit spreads
  • IV rank < 25 → penalty (selling cheap vol)
Group 5 · Liquidity (penalty up to −0.10)
  • Min open interest across all legs
  • OI < 100 → −0.10 · OI < 500 → −0.05

Skew (Wing IV − ATM IV)
DTE:
Wing Δ:
Metric:
Wing vs ATM
IV(put wing) − IV(ATM), in vol points

How much the OTM put trades above (or below) the at-the-money strike. Measures the height of the put-side tail relative to ATM — i.e. how expensive crash insurance is on this name.

  • Positive (typical) — wing IV > ATM IV. Standard equity put skew: portfolios bid up crash protection, so OTM puts trade richer than ATM.
  • Near zero or negative (unusual) — wing IV ≤ ATM IV. Flat or inverted put side. Common when there's no fear demand, in tightly mean-reverting names, or right after an earnings catalyst clears.
  • Percentile vs own 3-yr history: high = wings rich (good time to sell wing premium); low = wings cheap (good time to buy protection).
  • Not directional — high or low wings don't predict up or down moves. It's a price tag on tail insurance, not a forecast.
Risk Reversal
IV(call wing) − IV(put wing), equal delta on each side

Which side of the smile is the market paying up for? Measures the tilt of the surface — call skew vs put skew at matched deltas.

  • Negative (typical) — puts richer than calls. Standard equity behavior: hedging demand makes puts carry a premium. Most large-caps sit in the −1 to −5 vol-point range.
  • Strongly negative (< −5 pts) — heavy downside hedging, elevated fear, or an upcoming catalyst (earnings, FDA, macro event). Worth flagging.
  • Positive — calls richer than puts. Unusual for equities; signals bullish momentum, short-squeeze positioning, or takeover/M&A speculation.
  • Near zero — symmetric surface. Market sees roughly equal up/down risk. Rare for large-caps; more common in commodities and FX.
Reading them together

Wing-vs-ATM tells you how expensive the tails are. Risk Reversal tells you which side is favored. Combined:

  • High wing percentile + deeply negative RR → strong put bid; stress or major event priced in. Owning protection costs a premium; selling put premium is dangerous.
  • Low wing percentile + near-zero RR → complacency; insurance cheap and balanced. Good environment to add cheap downside hedges.
  • Positive RR + elevated wings → call-side fear-of-missing-out; common in squeeze setups. Upside calls expensive, downside puts not bid.

Percentile is the rank of today's reading within ~3 years of this symbol's own history. High percentile = wings are rich relative to history; not a directional signal. Skew is read off the chain in real time, not from CBOE SKEW.

Short Interest & Float

Regulatory short-interest reports publish on a bi-weekly settlement cadence; short-volume is reported daily by the trade-reporting facilities. Float is derived from insider-ownership filings.

Metric definitions
  • Short Interest — total shares currently sold short as of the settlement date. Lags real time by ~8 business days.
  • SI % of Float — short interest / free float. The key crowding metric.
  • Days to Cover — short interest / avg daily volume. How many full trading days it would take shorts to buy back. High DTC + catalyst = squeeze fuel.
  • Short Vol Ratio — today's short-sale volume / total volume. Intraday selling pressure proxy (not the same as short interest).
  • Free Float — shares available for public trading (total shares minus insider / restricted).
  • Float % — free float / shares outstanding. <50% = tightly held, more prone to squeezes.
How to read the signals
  • SI % of Float < 5% — typical, no particular signal.
  • 5–15% — elevated; watch for catalysts (earnings, guidance, macro).
  • 15–30% — heavily shorted; tight-float names in this range have produced notable squeezes historically.
  • >30% — extreme; borrow is likely expensive and squeeze risk is material.
  • Days to Cover > 5 combined with high SI% amplifies squeeze potential.
History chart
  • Trend matters more than level. Rapidly rising short interest often precedes negative catalysts or heavy hedging.
  • A sudden drop in SI after a rally may indicate a squeeze in progress.

Short interest is reported mid-month and end-of-month; short volume is daily.
